Xavier Noria 9b423ac0b7 let this regexp be stricter ...

The purpose of this regexp is to detect strings that
are valid identifiers to be used as method names.
The anchor $ allows a trailing newline, and both ^
and $ may be bypassed because Ruby regexps are
multiline always. The anchors \A and \z are the
proper ones to ensure string boundaries.
